While the bride – whose wedding might be gatecrashed by locals – hasn't confirmed any details about her dress, nor its designer, a source close to Deacon's team has reportedly let slip to E! News some key details with regards to her bespoke gown.

Described as being 'very simple, elegant and it's all handmade', the source reveals 'very few people have seen the finished thing'.

The source also added that Pippa has had her dress taken in a staggering five times over the last few months, rumoured to be as a result of her dramatic weight loss.

Pippa's former trainer Matt Roberts, who has worked with David and Samantha Cameron, recently told the Telegraph: 'I know she runs, swims, and does Pilates and gym work.' Sources say she and Kate work out in the gym at Kensington Palace, doing cardio, lunges, crunches, squats, planks and push ups.

'Getting ready for a wedding is very much like prepping for a triathlon or marathon. You have a clear time-line in mind, and the end date isn't moving anywhere, which is great for motivation,' he added.
